Specification forming part of Letters Patent No. 83,407, dated October 27, 1868.

To all whom 'it may concern:

Beit known that I, J ULIUs F.` QUIMBY, of the city of Troy, in the county of Rensselaer and State of N ew York, have invented certain new and useful Improvements in Water-Reservoir Cooking Stoves `or Ranges; and I do hereby declare that the following is a full and exact description of the same, reference being had to the annexed drawings, andthe letters of reference marked thereon, forming a part of this specificationfin whichi Figure 1 is a perspective view of a cookingstove, and showingmy improved water reservoiror tank attached thereto and connected therewith by my improved `manner of construction thereof. l Fig. 2 is a vertical longitudinal sectional view` taken at the dotted line x a: of Fig. l;y and Fig. 3 is a top or plan view of my improved water-reservoir cookingstove, with the reservoir-top plate and a part of the stove-top `plate removed to show more clearly my said improvements therein.

The same` letters refer tolike parts in each of the said figures. i A

My said invention consists in combining a chamber or flue-space, made around about the end sides and rear side of a water reservoir or tank, arranged at the rear end of a cookingstove, directly with the descending or diving iiue thereof, in such a manner that a portion of the 'esh unspent currents of heat going theredown are diverted therefrom before passing down under the oven, as formerly, and made to pass directlyrinto and horizontally through said `ilue space or chamber of the `water-reservoir, to thereby more eifectively heat or to boil water therein. j i

To enable others skilled in the art to make and use my said invention, I now proceed to fully describe its construction and operation, to wit:

In the annexed drawings, A represents a cooking-stove of the usual form of construction, and with the addition thereto, as made in and through its exterior rear or end side plate B, and at each side thereof, of the induction and exit apertures a and a', respectively, in manner substantially as shown in Figs. I and 3.

The hot-water reservoir C is constructed with a continuousflange or rim, D, projecting ontw ard from its top edges at its front, back,

and end sides. The bottom F of this reservoir likewise projects outward at and from its front and back and end sides, respectively and continuously. It has also a ridge or small `flange, l, upon and near the edge of said projecting flange or rim, that extends around the "ends and rear thereof, to aid in holding a casing or jacket to said reservoir-bottomedges. The respective end sides and rea-r side of said reservoir C are now inclosed by a jacket or casing, E, either of cast or sheet, tinne'd or zincked iron, which is secured to the respective top and bottom projecting flanges or rims D and F of said reservoir by rivets or bolts, or

by other suitable means, and in such a man-- ner as to form double end sides and rear sides 'for said water-reservoir C, and inclosing a space or chamber between said walls or sides, which, being full of air, retards and prevents thecooling of water in said reservoir, by retarding and preventing the radiation of heat therefrom by the non-conducting properties of air in said chamber between said double end sides and rear side of said water reservoir or tank; and the said chamber or space forms also a flue, G, which, being connected with the diving or descending iiue of the cooking-stove A, in manner as `hereinafter described and shown, forms a branch iiue therefrom, which diverts a portion of heat therefrom, that passes in horizontal direction around and between the aforesaid double end sides and rear side of said water reservoir or tank, substantially in manner as shown in Figs. 1 and 3 of the annexed drawings, to thereby more rapidly heat water in said water reservoir or tank G.

This water reservoir or tank, as thus constructed substantially, is now arranged at and attached by lugs and bolts, or by other suitable means, to the exterior wall or side, B, of a cooking stove or range, A, and in manner such that the projecting top and bottom edges of the anges or rims aforesaid, or the equivalent devices therefor, and the end side edges of the jacket or casing E of said water-reservoir, may make a close joint with the exterior wall or rear side, B, of a cooking-stove, so as to therebyform a transverse flue, b,` between the water-reservoir C and the exterior wall, B, of the stove, which separates the flue b from the stove-nues e and f, or theirV equivalent iiues, which are, by means of the induction and exit openings a and a aforesaid, connected with the said reservoir-Hue c, and the transverse flue b connects at each end with the ends of ue c, near the apertures a and a', in manner substantially as shown in Fig. 3 in annexed drawings. Y

The induction-openin g a is provided with a damper, d, with which to close it, whenever desired, so as to send ordivert allof the hot products of combustion under and through the oven-fines.

A damper, G, is arranged, in the usual manner, within the top iiue of the stove to shut off the direct draft to the exitlpipe, when so desired, to thereby send heat through the oveniiues, and also through the reservoir-fines c and b. rlhe reservoir-top is provided with the usual lids or covers.

To operate this improved water-reservoir cooking-stove, close the direct-draft damper G, and open the waterreservoir-flue damper d. The heated gases and products of combustion now pass to the descending flue e, thence through the induction-opening a into the reservoir-fines c and b, circulating therein around and about the sides and ends of said water-reservoir C, in the manner about as shown by the arrows in the annexed drawings, and so as to heat quickly and effectively, and keep hot water within said reservoir. The heated gases pass thence through the exitopening a into the rising exit-iue f, thence into the exit-pipe, as shown.

The amount of heat passing into said reservoir-lines is easily regulated by said damper d, by partially closing the opening a therewith, 4

so as to graduate the temperature of water in said reservoir from warm to hot and hot to warm, as may be wanted, and, when no hot water is wanted, entirely close said damper d, which thereby diverts all of the heated gases through the oven-fines.

This improved water reservoir may be adapted to and applied to three-lined and other varieties of flues in cooking-stoves by shifting, if necessary, the location of the exitopening a', so as to always connect it with the rising exit-fines of a stove, and by shifting, if necessary, the induction-opening a, so as to always connect with the descending or diving iiues thereof, thus shifting their positions, respectively, whenever necessary, to suit the particular arrangement of stove-fines in each case to which this improved water-reservoir.

may be applied.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. Combining the chamber or iiue c of a water reservoir or tank, C, when constructed and arranged with' a cooking-stove, substantially as herein described, with the diving or descending liuc e thereof, so as to divert a portion of the unspcnt currents of heat going theredown therefrom, and making them pass directly intoand horizontally through said iiue c without first passing under the stoves oven, 'as formerly, thus making said reservoir-fluec a branch flue of the diving-flue c, in manner substantially as and for the purposes hereinbefore set forth and shown.

2. Connecting each end of said branch flue c, when extending or passing in horizontal direction around the end sides and rear side of said water reservoir or tank C, as arranged at the rear-end side of a cooking-stove, respectively, with the diving and rising iues e and f thereof, by means of apertures a and a in the stove, opposite to the ends of said flue c, in manner substantially as described and shown, for the purpose set forth.

3. The combination, witheach other, of the extended or branch iue 0,-passin g in horizontal direction around the end sides( and back side of a water reservoir or tank, C, they crossflu'e b, as passing in horizontal direction and connected at each end with said flue c, and the diving and rising ues c and f, as connected with the respective ends of said extended flue c by apertures a and a', when all of a waterreservoir cooking stove, and relatively arranged in manner substantially as herein described and shown, for the purpose set forth.

4. Incombination with the damper G, bran ch iiue c aforesaid, and the aperture a. in the diving-flue e, the employment of a damper, d, to close the opening to said ue c, to shut oft' Vall currents of heat therefrom, and thus make of said iiue an air-chamber, for the purposes as hereinbefore set forth.
